The invention further provides a system suitable for preparing ethylene and propylene and the use thereof. wo 2014/005996 AI III llll IIII III III Hill III III III Hill Hill llll llll llll 111 111 lllllll llll llll Declarations under Rule 4.17: Published: — as to applicant's entitlement to apply for and be granted — with international search report (Art. 21(3)) a patent (Rule 4.17(H))
